Hi, ardvark,
I like that you are being brave and letting them be heard. It will be therapy for them. Your inner children have the same needs as outside children plus their trauma needs. Listening to them is important.
I found that making collages of things torn out of magazines and catalogues very helpful. I let myself tear or cut out whatever picture had a feeling associated with it. I didn't need to know what each picture meant during the time I was collecting them. Sometimes it was scary. This time of year is hard for me and there were plenty of scary faces and figures in the Halloween adds. As I taped the pictures together, I would find a central image and add on to it in a free form style being careful not to dictate who it looked. For example I had pulled out a fancy whiskey add with a velvet bag. I let my hand float above to find where it went. I already had an Elizabethan figure in full costume with the huge ruff around her neck (I don't remember if she had a head but not scary). The fancy whiskey belonged next to her.
I keep crayons and white computer paper around. I use the thick crayons because they felt the same to my adult hand as in proportion to a child's hand. Again, I try not to direct the drawings, or scribble scrabble, or color or words. Coloring time was an opportunity for little ones to be busy at something all kids like to do. It gives them recognition, and most importantly it lets them express how they are feeling. Don't be sad if some pictures look angry or sad. That is good!!! You can take both the collages and crayon drawings to your therapist to figure them out.
I took walks to the local children's park and sat on the tire swing for a little while especially when no one was around.When we came home, I made hot chocolate instead of coffee. Now we drink mocha a lot.
I bought small packages of applesauce, and pudding. Once in a while I would just relax and let someone little fingerpaint on my kitchen table with pudding. They liked to put the fingers in thing and explore the texture. Once I caught on I bought tapioca pudding as well.
That's just a few ideas, Oh, I forgot a stuffed animal is good, I think the Discovery Store has aardvarks.
It is a long process to gain their trust and recover their memories but it is very worthwhile work.
